Structure of Superconductive Vortices near a Metal-Air Interface

Abstract

The current distribution along a vortex line emerging from a bulk superconductor is computed. The current density at the metal‐air interface was found to follow a 1/r² law at far distances from the vortex axis, while deep inside the metal it falls off exponentially. The effect of this structure on the macroscopic behavior of superconductors is discussed.
